A Deeper Dive

Although it draws inspiration from our original 1970 design, the Bathysphere GMT is a thoroughly modern watch, with a 43 x 49 x 15 millimeter case CNC machined out of a solid block of German 316L surgical stainless steel.
 
The caseback and crown screw tightly down to ensure a water resistance of 1,000 meters (3,333 feet) and, should you find yourself in a helium-enriched diving bell, the case is equipped with an automatic gas relief valve nestled between the strap horns at 12:00.
 
The steel bezel is topped with a scratch-resistant and luminescent ceramic timing ring and precisely ratchets through 120 positions, allowing you to time everything from decompression stops to pizza deliveries.
 
Inside ticks a self-winding Swiss movement, the ETA 2893-2, which drives hours, minutes and sweep seconds, a quickset date function, and a GMT hand that allows for tracking of a second time zone when used in conjunction with the 24-hour scale on the dial.
 
Befitting a capable watersports watch, the Bathysphere 100 GMT comes fitted with a 22-millimeter ISOfrane rubber strap with stainless steel Aquadive-signed buckle.
 
The Bathysphere 100 GMT is limited to 500 pieces (of each color) and the individual number is engraved on the caseback.
